Testing Klairs products together and WHAT! Total fail for me.

First I will just say, that I have no problems with the brand Klairs at all. I just noticed that it looked weird on my skin and wanted to see what really happens.
These products are bought by me from Wishtrend some time ago, and I have always had the same problems with them. I just had them stored, and every time I tested them I got the same result. I don’t know it I got a bad concealer or if there are anybody else out there who have the same experience
